The Slotted Conical Disk Spring
(The American Society of Mechanical Engineers (ASME), 1973)The slotted conical disk spring is a modification of the regular conical disk spring or Belleville spring inasmuch as it has regularly arranged slots extending from the inside diameter. A ... -
Closed Form Synthesis of Spatial Function Generating Mechanism for the Maximum Number of Precision Points
(The American Society of Mechanical Engineers (ASME), 1973)A general closed form method of planar kinematic synthesis is applied to spatial function generating mechanism for up to the maximum number of precision positions. Computer programs are written ... -
The Study of Adjustable Oscillating Mechanisms
(The American Society of Mechanical Engineers (ASME), 1973)The basic principles of linkages with adjustable output oscillations are discussed. It is then shown how to design six-bar linkages with adjustable output-oscillation angles. The kinematic analysis ... -
Synthesis of an Eight-Link Mechanism for Varieties of Motion Programs
(The American Society of Mechanical Engineers (ASME), 1973)Using the matrix approach, synthesis equations are derived for eight types of synthesis problems for an eight-link mechanism having five links in each of its three loops. A numerical approach ... -
Analysis and Design of Cam-Driven Mechanisms With Nonlinearities
(The American Society of Mechanical Engineers (ASME), 1973)The cam-and-follower mechanism is represented by a lumped parameter model of finite degrees of freedom, in which nonlinear system parameters may be taken into account. An approximate dynamic ... -
Analysis of Spatial RRGRR Mechanisms by the Method of Generated Surfaces
(The American Society of Mechanical Engineers (ASME), 1973)The motion of a spatial RRGRR mechanism can be determined by considering the intersection of two tori. In this paper the intersections of two offset skew circular tori are found, thus defining ... -
Analysis and Synthesis of Mechanical Error in Linkages—A Stochastic Approach
(The American Society of Mechanical Engineers (ASME), 1973)A stochastic model of the four-bar linkage considering tolerances and clearances is made. The mechanical error is analyzed for the three-sigma band of confidence level. The effectiveness of the ... -
Some Elementary Projective Properties of the Four-Bar Linkage
(The American Society of Mechanical Engineers (ASME), 1973)The four-bar linkage defines a complete quadrilateral—a figure with extensive elementary projective properties. The undertaking is to search out and discover evidences or indicia of projective ... -
On the Distribution of the RMS Shaking Moment of Unbalanced Planar Mechanisms: Theory of Isomomental Ellipses
(The American Society of Mechanical Engineers (ASME), 1973)It is shown that the RMS shaking moment of unbalanced planar mechanisms is constant with respect to all points along certain concentric ellipses (isomomental ellipses) in the mechanism plane. ... -
Analysis of Elastic Machinery With Clearances
(The American Society of Mechanical Engineers (ASME), 1973)Previous work on the analysis of elastic link mechanisms has been enlarged upon so as to include the effect of intermittent separation and impact between members. A cam-driven valve train is ... -
Necessary and Sufficient Existence Criteria of Overconstrained Five-Link Spatial Mechanisms With Helical, Cylinder, Revolute, and Prism Pairs
(The American Society of Mechanical Engineers (ASME), 1973)Dimentberg’s approach of passive coupling is extended to develop necessary and sufficient conditions for the existence of five-link spatial mechanisms with helical, cylinder, revolute, and prism ... -
Some Advantages of Product Criteria in Component Optimization
(The American Society of Mechanical Engineers (ASME), 1973)In optimum design the optimizing criterion is a mathematical compromise among performance, cost, life, and conformity to constraints. This paper makes use of the fact that for every linear sum ... -
A Proposed Prosthesis for the Lumbar Spine
(The American Society of Mechanical Engineers (ASME), 1973)This paper chronicles a kinematic study of the lower spine. The synthesis of a four-bar mechanism to serve as an implanted appliance is shown. The device and the radio-logical technique for ... -
Synthesis of Kinematic Chains via Method of Cut-Set Matrix With Modulo-2 Operation
(The American Society of Mechanical Engineers (ASME), 1973)Method of cut-set matrix with modulo-2 operation is used to enumerate all possible tree graphs from a given tree graph. The typical kinematic chains corresponding to the tree graphs are the ... -
Closed Form Displacement Relationships of Single and Multi-Loop Six-Link Spatial Mechanisms
(The American Society of Mechanical Engineers (ASME), 1973)Using (3 × 3) matrices with dual elements, two loop Watt and Stephenson type six-link spatial mechanisms with one revolute and six cylinder pairs and single loop R-C-R-R-P-R, R-C-R-R-R-R ... -
Elastohydrodynamic Lubrication of Involute Gears
(The American Society of Mechanical Engineers (ASME), 1973)A criterion is suggested for the application of the steady state elastohydrodynamic theories to the analysis of involute gear contacts. The criterion is based on a comparison of two physical ... -
